Everybody knows that the best thing about Marvel films, well, after all the action and on-screen hotties, is the sneak peek of what's to come for the next big movie!

Captain America: The Winter Soldier is no different!

After the Avengers' post-credit scene, the film teased the audiences with Thanos being a possible villain for the highly anticipated Avengers: Age of Ultron.

Thanos may appear in the Avengers sequel, but we now have a clear idea of who will be providing all the evilness in Age of Ultron after seeing the post-credits scene in Captain America!

When the main, major credits rolled all the way through, SPOILER ALERT: Do not continue reading if you don't want any hint at what's to come for the Avengers sequel!!

After Baron Wolfgang von Strucker appears on the screen, who is believed to be the next villain in Avengers: Age of Ultron, and is mulling over everything that just happened throughout the film and then he looks up after saying, "the Twins."

And, lo and behold, we get the glimpse we've all been waiting for, they show the two new additions to the Marvel movies, Quicksilver and Scarlet Witch!!

The two may not have looked like much, considering the fact that they were both stuck in two cells, but we're pretty sure they're a force to be reckoned with.

Elizabeth Olsen and Aaron Taylor-Johnson have been tapped to star in the Avengers sequel, but what does Baron Wolfgang von Strucker have in mind for these two?!

Take a look at Elizabeth and Aaron in all their superhero glory (below)!
